Store fly screen winter: wash it, then take it down

The flies have gone, the sheet is still on the uPVC, and the south-facing tape has had a whole summer. Storing a fly screen over winter is mostly a decision about adhesive, not about insects. tesa's UK window page tells you to take the screen down, store it, and reuse it. Leave the glue through the sun and the short days, and you spend March scraping a frame.

The mesh and the door curtain do not share one care label. A window sheet can go through a 30°C wash. The magnetic curtain's PDF says hand wash, and it says you must not trim the mesh. The Products Compared editorial team used those tesa pages, Family Rollo on leftover glue, Everest's uPVC cleaning advice, and the amazon.co.uk listings in our tesa fly screen comparison. We did not run a wash test. A qualifying purchase can earn us a commission at no extra cost to you.

In short

Take window sheets down before winter, wash them at 30°C if they need it, dry them, and store them. Do not machine-wash the magnetic curtain, and do not cut it to fit a box. Sun-hardened tape is the damage. Replacement tape is cheaper than a ruined frame.

Why summer adhesive is a winter problem

Hook-and-loop fails slowly. In June the strip lets go at a dusty corner. In October the same strip can look fine and still be cooking. Family Rollo, writing about glue left after a mosquito net, says adhesive left through sun and seasons is harder to lift, and that you should take screens down. A UK winter does not switch the sun off. Low sun on a south or west frame still warms uPVC, and a heated room warms the inside face.

tesa's window fly-screen page is plain about the calendar: remove the screen and store it over winter, then reuse it. Insects are not the reason to keep it up from November to March in Britain. Pollen, dust, and condensation are what the mesh collects while it does nothing useful. You then wash a dirtier sheet, or you throw it away because the tape tore.

If you still open the window on mild October evenings, leave the sheet until you have actually stopped. Once the sash stays shut for weeks, take it down. Do not wait for a spring clean. South-facing tape that stays up just in case is the tape that will not peel in one piece. Storing the screen is what tesa describes. A promise that the same adhesive will work for years is not on that page. The mesh is reusable. The strip is a wearing part.

Window sheets: wash, dry, store

tesa's UK window page says you can machine-wash these screens at 30°C. The anthracite Comfort sheet that is the top pick here for a tall French window, 120 cm by 240 cm at £9.51, lists wash up to 30°C as well. It has 4.4 out of 5 from 17,369 reviews on amazon.co.uk. Those reviews are not a laundry trial. Hotter water is how people shrink or stiffen a net they meant to store.

Wash it when pollen, kitchen film, or fingerprints have closed the holes. A short 30°C cycle, with no bleach and no tumble dry unless the listing says so, is as far as these pages go. Shake dust off outdoors first if the sheet is only dusty. Dry it completely before you fold it. Damp mesh in a bag sweats. Fold loosely, in a dry cupboard, away from a boiler. If you have two sizes, label them. The 120 cm by 240 cm sheet is for a tall opening, and cut to size is not stated on that Comfort listing, so do not slice it in the autumn.

The white Standard sheet at £7.20, 130 cm by 150 cm, is the same family: trim where the listing allows, wash at up to 30°C, and take it down. Open/Close at £23.99 is still a window screen you store, not a cassette you leave in the rain. None of those prices includes a promise about the tape's second summer. Put the sheet where you will find it in April, with a note of which window it fitted.

The magnetic curtain is a different care line

The magnetic curtain is not a long window sheet. tesa's product PDF says hand wash. The page body also says hand wash. A machine-wash sentence appears elsewhere on tesa's own material and conflicts with the PDF. When the brand disagrees with itself, follow the PDF. Do not put the curtain in the machine because a window-sheet page said 30°C.

Do not trim the curtain to tidy it for a box. The PDF and the listing say the mesh is not cut, because cutting shifts the magnets. You may cut fixing tape to the frame when you fit it. Roll or fold the whole stock size. The choice of curtain versus sheet is on window sheet or magnetic door curtain. The PDF also says residue-free removal: no. Buy the next stock size if this one is tired.

If you only own window sheets, do not borrow the curtain rules by accident because both products say Insect Stop on the packet. Check the listing you actually bought. Twelve listings sit in the comparison. The wash symbol from a different pack is how the wrong care line starts.

Taking tape off a frame

Peel the mesh from the loop first, so you are not fighting a square metre of cloth while the adhesive lets go in patches. Then lift the tape from the frame in a warm room. Cold tape snaps. A hairdryer on a low setting, kept moving, softens many strips. Park it on one spot and it can soften uPVC, so this is a short pass. If the strip comes away in one piece, you are finished with that edge.

If it comes away in islands, stop scraping like a decorator on glass. Everest's guide to cleaning uPVC windows and doors warns against acetone-style aggression and bans several solvents on the plastic. A shiny, dulled, or sticky-melted frame is worse than a thin glue line. Use a plastic card flat, not a metal blade at an angle. Family Rollo's point stands: glue that has seen sun and seasons is the glue that fights you.

If the film will not move, stop before you dull or melt the frame. Warm the room, lift slowly, and use a plastic edge flat.

Rented frames need a photograph before and after. Owned uPVC is not a surface to practise solvents on. Wood can lose finish if you flood it, and aluminium can take a different cleaner from plastic. Do not sand the residue. Sanding uPVC leaves a matt scar. The mesh cost less than a new sash.

Putting it back next spring

Refitting is the same order as the first fit, not a new invention. Clean and dry the frame, stick tape without overlaps, press the mesh, then trim only if that sheet is sold as cut-to-size. The steps live on how to fit a tesa fly screen. What changes in spring is the condition of last year's strip.

If the old tape is dusty, stretched, or shy of the frame, bin it. The Comfort listing for the 120 cm by 240 cm sheet says replacement hook-and-loop is available. A Standard sheet you trimmed last year is already the size of that window. Do not trim it again unless the edge has frayed into a hole.

Close and lock the sash once. An outward-opening window that locked in June can fail in April if the new tape sits thicker in the closing path. On a bedroom window you might need to climb through, the mesh still has to clear quickly. Storage did not turn a sheet into an escape approval. The useful end of winter is a dry sheet, a bare frame, and a new strip if the old one is tired.
